Vim: use text properties?

[blueyed]

Is Vim 8 supported?
No. Semshi relies on Neovim's fast highlighting API to quickly update lots of highlights. Regular Vim unfortunately doesn't have an equivalent API. (If you think this can be implemented for Vim 8, let me know.)

You could use text properties in Vim probably.

Pseudo / Python code (from my WIP for jedi-vim using it to highlight usages):

if not vim_prop_type_added:
    vim.eval("prop_type_add('jediUsage', {'highlight': 'jediUsage'})")
    vim_prop_type_added = True

vim_prop_add(lnum, start_col+1, {
    'type': 'jediUsage',
    'bufnr': buf.number,
    'length': length,
})

JFI.
As for Neovim there are nice changes planned using tree-sitter for 0.5. Are you aware of them?

Ah, thanks, that sounds helpful! I'm going to look into that.

I saw it come up a few times on the issue tracker - is there a current ticket/PR?

In theory, being able to take advantage of tree-sitter's incremental parsing would be a huge upgrade. However, Semshi doesn't just parse the syntax, but also determines scopes, etc. That is, Semshi also needs symbol lookup logic, whereas tree-sitter AFAIK only provides grammar parsing. Updating symbol tables incrementally seems like a challenge on its own.
